Honestly I love the way you teach, I've been watching your videos even before I get certified and you helped me a lot with your content for the exam, I hope one day to be as skilled as you
Woah, I just randomly found this video in my recommended, and after listening to you for a bit I realized "Holy Crap, I'm taking this mans CCNA course on Udemy" Amazing course btw!
Just purchased your CCNA course. I first completed CCNA and CWNA back in 2005.. it's been a while. Your course looks very well structured and looks practical/interactive. For $10 bux I highly recommend it. Will post more feedback after I've completed it.
I honestly didn’t think this was possible it took me like forever to figure something out, tried different ways to get back my IG acct That was blocked a long time ago but no one was able to help , my friend told me to try @crowns_hack23 on Instagram and so I did Great news! It worked!!! If you’ve been looking for a way to get yours back, don’t fail to reach out to , he is really amazing 🤩
Great video, well done David! I started to use yersinia and macoff as an ethical hacking tools, collecting logs in 2015. One of my customers didn't believe that someone could stop his network. We scheduled a non business hour and I flooded his network with more than 65000 mac addresses using two simple linux. His switches collapsed within mac moves notifications. Even his uplinks and downlinks entered in error-disable mode. There was upon a time when dot1x came out to play...
David, you are a master at explaining complex topics thoroughly yet with such concision. Very easy to follow along & you have such a wealth of knowledge. Thank you for taking the time to post these videos on ethical hacking techniques to help people, such as myself, protect their personal IT environment.
@@natural......9963 It's automatic because I have a membership with David Bombal ($1.99/mo). It's like Patreon, but through RUclips. Other plans are available, each with specific perks. I've learned a lot from his videos & David's time is of value to me. When I thought about how much I spend on books (that take hour[s] to absorb) versus watching a 30-min video demo, the $2 seems a pittance. Notice the comments to his videos: they are overwhelmingly positive & full of gratitude. Thanks.
It has been one of the most meaningful videos, God bless you for the information you have given, you are a perfectly knowledgeable and intelligent person. Living at the same time with you gives me great pleasure.

Just passed my CompTIA Network+ last month and I'm glad I was able to follow along (for the most part). Saw some new Cisco protocols that weren't covered in Network+, I didn't know CDP? Have to look those up along with the program tools. Obviously Cisco proprietary protocols. With so many Kali tools it was good to see a list of them on tools.kali.com. Now I can go and research all of them and see what's available. Awesome content, and don't be afraid to plug your courses. You put out the best explanations and walk throughs.
Easy & effective. I've been learning ethical hacking for a long time so that's nice to come back and see Yersinia. I'm looking forward to see more videos from you.
I became interested in hacking due to boredom during the pandemic. I did some research. Found Kali. Downloaded it with someone’s instructions ( won’t name you tubers name). Then had to delete it along with the VM. Did this about 3 times until I found you and the dude with the beard. 🤔.... forgot his name. Something chuck. Point is thank you both so very much for allowing me, which had no computer knowledge whatsoever, I mean, I would create a profile and immediately couldn’t log back in. Lol. Thanks guys

Hello David! Thank you for this course! I'm an application security tester learning infrastructure hacking to conduct full pentest engagements. This is great help for me to move forward in my career! Question is there a way you can create this lab without a Cisco switch? Can this be done with GNS3 and configure it as a Cisco Network?
Loving the "Afrikaans" accent thanks David !!! David im currently in the Insurance Industry , what will be the best way for me to get into the IT Sec industry in SA? Warmest regards and keep up the great work!
Thank you JC. I have lived in the UK for many years. Not sure about the dynamics and best options in South Africa. But, I suggest you try networking with people in the industry locally via LinkedIn or going to meetups and the like.
This topic is super complex for beginners ! wished an explanation to the network protocols as that is super advanced for the first video after kali installation
Assuming you can get physical access to an unsecured switch.... anyone with security that poor deserves to get hacked. Still, a useful tutorial for network admins who want to make sure their networks are hardened. Thank you.
Agree with Abdi's comment. Having programming knowledge is always an advantage. Start with the basics and then build on that knowledge. Remember that everyone at one point in their lives didn't know anything about networking or hacking. Everyone had to learn.

Can someone please tell me what accent this great man has? I would like to know. English is not my native language, I just learn it. And this man has such a clear pronunciation and a pleasant voice!
finally somebody shows a realistic looking rack room in his intro. Whenever anybody shows a rack room it usually looks like a goddamn ufo spaceship. Reality is usually a jungle of cat5 and fiber
Not sure if you still read these but I tried to load yersinia with the "yersinia -G" and it doesn't do anything. No error message, nothing. Any idea why it would behave like that? The -h prompt works as it should
apparently you need an external USB adaptor now to make it work using yersinia, there's nothing that can be done about this, from my knowledge. I don't know much about this either as i am a beginner myself.
hello, i have loved your video so far, but i am having problems with installing yersinia. this is what happens when i tried it. my kali linux is the 2020 version. kali@kali:~$ sudo apt-get install yersinia Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package yersinia it seems weird that i had to type 'sudo' before certain commands, and i dont know what that means. i have a really strong will to become a hacker, but i am absolutely clueless about computer programming and i know nothing about hacking. im really interested in this topic and would like to learn more about it. could you please further explain about the commands you used? e.g. what does 'apt-get' do and where else can i use this command? what does 'sudo' means? also it would mean a lot to me if you could tell me more about how to become a hacker. where should i start? which programming language should i learn first? sorry that i have a lot of questions, but i am generally intrigued, could you please tell me more? finally, thanks a lot for these videos, they are very clear and if i do a bit of research, even a dumb dumb like me is able to understand. keep up with the videos! i love them.
sudo means that you need to ask for permission to do certain functions as you are not a root user. you will not be a default root user in kali linux 2020

hey David h r u, thanks for your videos on Ethical hacking. I learn a lot. It is my humble request to you please bring one complete series on Ethical hacking from scratch to Pro. I hope you will.
I have every reasons to do what I had to do if you were in my shoes! I couldn’t take it any longer, I had spent over thousands of dollars on medication but she couldn’t stop. She was a drug addict, I realized a bit late through her text messages and recent call records to different hard drug dealers. She had gotten to the point of selling them for a living and I noticed she’s always spending lavishly and never thought of our kids and I thought that was enough until she brought a man to our bed while I was away to satisfy her sexual urge. I got all the information from her through the great service of *ONE HACkER WHITE on IG, WhatsApp +1424-254-8116* I won’t have known if I didn’t take this bold step. I ended everything when we got to court with the concrete evidence I got! I’m happy to live a life without her unnecessary act
idk why most advertising or tutorials about ethical hacking has people who wears this kind masks, i mean, hollywood hurt people so bad lol But this is a nice tutorial i love him, i follow you from udemy.
@@davidbombal that could be right hahha master david, but im not agree people reffers to hackers with people with masks xD, but is the stereotype, i follow 70% of your courses, they're really nice david, thank you for share your knowledge.
I am teaching concepts in this video and have privilege 15 access (or root as you say) to demonstrate concepts. However, that level of access is not required to successfully launch a lot of the Yersinia hacks like CDP, VTP, STP or DHCP etc. These are layer 2 attacks that do not require any type of user authentication or authorization. Best practice would be to enable root guard, port security, dynamic ARP inspection, DHCP snooping and other mitigation techniques. The videos in this series teach why those types of protocols and mitigation techniques should be enabled.
@@davidbombal David Bombal my point is, you can confirm the attack is successful, how would an attacker know. And u know the switches setup with default config. Whether it be layer 1,2,3 core switch or even a layer 7 firewall you just flooding the switch with random traffic, which most Cisco's will disable that port and your "hacking" is being locally connected? . So the video then is mis titled hacking, I mean you could do the same with multiple computers doing a simple ping - l xxxxx. It's not hacking is all I'm saying, it's denial of service.
@@travismailsa1 When teaching concepts like these, I believe it is really important to demonstrate the results of the attacks. I would get a huge number of complaints if I didn't show the results of the attacks; and also set the foundation of what we are doing. This is also only one of the videos in the series and as I said in the video that it is getting too long, so I put more information in Part 2 and more in subsequent videos. I am showing attacks from the ground up - from initial installation in the first video in the series to more complex attacks. Probably best that we agree to disagree on this.
@@davidbombal I concur :) maybe change the video title, because that's why I came to watch. I thought it would of been a bug/firmware exploit or a Medusa or ripper attack from kali. Your video is well presented though. Finally :) if you teaching from the ground up and performing an "attack" locally advise on a Mac change.

A tip for Linux beginners: if you aren't logged into root, you will have to type "sudo" (without the quotation marks) before your terminal command.
Thanks!

I'm waiting with impatience for the next Part. Greetings from Poland :)
Coming soon :)
This topic is super complex for beginners ! wished an explanation to the network protocols as that is super advanced for the first video after kali installation
Assuming you can get physical access to an unsecured switch.... anyone with security that poor deserves to get hacked. Still, a useful tutorial for network admins who want to make sure their networks are hardened. Thank you.
Hello I have a problome with the Yersinia , yersinia Gui is not open i can use but in CLI not Gui , Gui is not open please Help me.
Hey, David
Do I need to know how to code to be in cybersecurity filed / or to be a hacker?
Not necessarily but the more you know about coding the better you can create your own scripts instead of using pre made ones
Agree with Abdi's comment. Having programming knowledge is always an advantage. Start with the basics and then build on that knowledge. Remember that everyone at one point in their lives didn't know anything about networking or hacking. Everyone had to learn.
if you work app security engineer ,you need to lean html ,java script ,
If you don't code your programs, you're a script kiddy.
Clara Jane god no no don't you ruin you life can't you just simply ask him instead of crushing his privacy
this is great!
I'm in for the entire Series>!
great explanation . keep it up
Thank you Santiago! Hope you enjoy the entire series :)
From zero to Hero. thank you so much sir, looking forward for Part 2 :).
Im a mechanical engineering student lol, but i find this very very interesting, and you look highly highly professional sub from me!!!😀
I love your intro/theme song!! Best I have seen
Thank you Melinda!

Can someone please tell me what accent this great man has? I would like to know. English is not my native language, I just learn it. And this man has such a clear pronunciation and a pleasant voice!
finally somebody shows a realistic looking rack room in his intro.
Whenever anybody shows a rack room it usually looks like a goddamn ufo spaceship. Reality is usually a jungle of cat5 and fiber
0:10 which laptop it is name plz ?
i don't not know
Asus vivabook
I’ll let you know when I find out
Your video is awesome , thank you so much
Appreciate the support Khaled

"I'm gonna have to go into hardcore hacking mode"
Thanks!
Not sure if you still read these but I tried to load yersinia with the "yersinia -G" and it doesn't do anything. No error message, nothing. Any idea why it would behave like that? The -h prompt works as it should
same🥲. Have u had the answer yet?????
apparently you need an external USB adaptor now to make it work using yersinia, there's nothing that can be done about this, from my knowledge. I don't know much about this either as i am a beginner myself.
@@nan_x3 legendary thank you for the update
hello, i have loved your video so far, but i am having problems with installing yersinia. this is what happens when i tried it. my kali linux is the 2020 version.
kali@kali:~$ sudo apt-get install yersinia
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package yersinia
it seems weird that i had to type 'sudo' before certain commands, and i dont know what that means. i have a really strong will to become a hacker, but i am absolutely clueless about computer programming and i know nothing about hacking.
im really interested in this topic and would like to learn more about it. could you please further explain about the commands you used? e.g. what does 'apt-get' do and where else can i use this command? what does 'sudo' means?
also it would mean a lot to me if you could tell me more about how to become a hacker. where should i start? which programming language should i learn first?
sorry that i have a lot of questions, but i am generally intrigued, could you please tell me more?
finally, thanks a lot for these videos, they are very clear and if i do a bit of research, even a dumb dumb like me is able to understand. keep up with the videos! i love them.
sudo means that you need to ask for permission to do certain functions as you are not a root user. you will not be a default root user in kali linux 2020
Interesting contents and well explained . Thanks !
Thank you
I tbh dont get anything im just scaring my mom into giving me the tv remote

Shortly before commenting on here, I saw countless recommendations about @tiana_john20 on Instagram so I had no options than to contact her so you know what,she proved her worth and cleared my doubts @tiana_john20 she is 100% legit 🤡🤡
I really like your topics, Thanks a lot Mr.David
hey David h r u, thanks for your videos on Ethical hacking. I learn a lot. It is my humble request to you please bring one complete series on Ethical hacking from scratch to Pro. I hope you will.
Me: about to go to bed
RUclips: Wanna learn how to hack?
I hack my girlfriend phone and now she broke up with me
ohh..no
xDDDDDDD
Can you help me in hacking bro please
Explanation plz
Cyber_zest is the most accountable hacker i have came across during my quest to recover my lost instagram account
Wow, i have seen 2 minutes of videos and i can hack girl's heart lol
Lol. Girls have got so advanced that they have their side Kali safeguarding them.
😂😆
Lol

I have every reasons to do what I had to do if you were in my shoes! I couldn’t take it any longer, I had spent over thousands of dollars on medication but she couldn’t stop. She was a drug addict, I realized a bit late through her text messages and recent call records to different hard drug dealers. She had gotten to the point of selling them for a living and I noticed she’s always spending lavishly and never thought of our kids and I thought that was enough until she brought a man to our bed while I was away to satisfy her sexual urge. I got all the information from her through the great service of *ONE HACkER WHITE on IG, WhatsApp +1424-254-8116* I won’t have known if I didn’t take this bold step. I ended everything when we got to court with the concrete evidence I got! I’m happy to live a life without her unnecessary act
Gonna like and comment every Bombal video that is relevant to my learning track. That's all 'em, just about. (Deep breath...)
After watching this vlog I want to learn atleast something about hacking, thank you david sir!
Aqui é BRASIL 🇧🇷 VALEU AMIGO♧
Damn I love ur office
Thank you :)
I need a video of Instagram hacking please make a video on this topic
lol
@@jeroeng1025 🤦
Great information dear sir. I m inspire to learn this Networking best skill .
idk why most advertising or tutorials about ethical hacking has people who wears this kind masks, i mean, hollywood hurt people so bad lol
But this is a nice tutorial i love him, i follow you from udemy.
lol... yes...you have to dress a certain way - right?
@@davidbombal that could be right hahha master david, but im not agree people reffers to hackers with people with masks xD, but is the stereotype, i follow 70% of your courses, they're really nice david, thank you for share your knowledge.
Pretty useless video. you have root access to the switch
I am teaching concepts in this video and have privilege 15 access (or root as you say) to demonstrate concepts. However, that level of access is not required to successfully launch a lot of the Yersinia hacks like CDP, VTP, STP or DHCP etc. These are layer 2 attacks that do not require any type of user authentication or authorization. Best practice would be to enable root guard, port security, dynamic ARP inspection, DHCP snooping and other mitigation techniques. The videos in this series teach why those types of protocols and mitigation techniques should be enabled.
@@davidbombal David Bombal my point is, you can confirm the attack is successful, how would an attacker know. And u know the switches setup with default config. Whether it be layer 1,2,3 core switch or even a layer 7 firewall you just flooding the switch with random traffic, which most Cisco's will disable that port and your "hacking" is being locally connected? . So the video then is mis titled hacking, I mean you could do the same with multiple computers doing a simple ping - l xxxxx. It's not hacking is all I'm saying, it's denial of service.
@@davidbombal also in your guide, maybe teach the guys su/sudo apt-get update/upgrade/install.
@@travismailsa1 When teaching concepts like these, I believe it is really important to demonstrate the results of the attacks. I would get a huge number of complaints if I didn't show the results of the attacks; and also set the foundation of what we are doing. This is also only one of the videos in the series and as I said in the video that it is getting too long, so I put more information in Part 2 and more in subsequent videos. I am showing attacks from the ground up - from initial installation in the first video in the series to more complex attacks. Probably best that we agree to disagree on this.
@@davidbombal I concur :) maybe change the video title, because that's why I came to watch. I thought it would of been a bug/firmware exploit or a Medusa or ripper attack from kali. Your video is well presented though. Finally :) if you teaching from the ground up and performing an "attack" locally advise on a Mac change.
Love it.

Possibly the video is mirrored? I know some cameras do it by default as that's how you see yourself in the mirror.
LamayzePY Probably
Ask me again? Sir, I subscribed the channel at a glance. I love hacking the most.
Thanks!

@@zestnelson9208 Hows the journey going xd? Also would you say this is for beginners
@@zestnelson9208 I’ve honestly seen several comments like this, I’d recommend you stop.
@@zestnelson9208 Upon further inspection, you have done this on every single video.
